7.1 x 4.2 x 3.7 cm. A classic golden group of gemmy, scalenohedral Calcite crystals with sharp, lustrous faces and great form sits on a matrix of sugary grey Quartz. Not nearly as common on the market as they once were, and are easily some of the most well-known American Calcite specimens extant.
3.5 x 2.6 x 1.8 cm. Dozens of small, sharp, sparkling, bright, elongated, dendritic Silver crystals sit atop a matrix of white Calcite. This specimen came out recently when a local collector was able to liberate some specimens from the dumps of this historic mine. The Balcoll Mine was worked as far back as the middle ages, so the fact that anything remained (even on the dumps) is amazing. A beautiful specimen with great character and aesthetics. Ex. Brian Kosnar Collection.
11.0 x 8.5 x 7.0 cm. An old-time, classic, cabinet specimen from the famous iron mines of Egremont, England. Stout, glassy, transparent, colorless to hematite-tinted pink calcite scalenohedrons richly and aesthetically cover the mounded matrix of hematite ore on this fine piece. The calcite crystals are up to 3.3 cm long and have unusual, modified, three-sided, pyramidal, terminations. This is a very fine large example of this important calcite varietal from this historic locale. Probably 100 years old or older.
10.6 x 7.7 x 3.6 cm. A fine cabinet plate from the famous finds in the late 1990s at the Meikle Mine of Nevada. Sharp, transparent to translucent, amber baryte blades richly cover the thin matrix crust. Many of the barytes are preferentially coated with tiny, colorless calcite rhombs, which add character. Crystals reach 3.0 cm on this fine piece, which is essentially pristine. Specimen of this gemmy quality only come from recycled advanced collections.
11.5 x 8.8 x 9.0 cm. A very attractive cabinet cluster of large, disc-like flattened calcite rhombs on a bit of matrix from an uncommon Washington locale - Metaline Falls. The highly lustrous, translucent, colorless crystals are up to 7.5 cm. Complete-all-around. From the very well-known Miller Calcite Collection sold in the 1990s. Rarely available on the market and this is excellent quality.
6.4 x 5.8 x 3.2 cm. A fine specimen of classic, light blue baryte prisms on sugary calcite from the Sterling Mine of Colorado. The large water-clear, windowpane with nice beveled edges measures 2.2 x 1.7 cm. Baryte has been known from this classic Colorado locale since the 1870s and this specimen probably dates from the 1970s to mid-1980s collecting efforts. Highly representative of the locality.
18.5 x 11.8 x 7.8 cm. A dramatic, very attractive large cabinet calcite specimen from recent finds at Santa Eulalia, Mexico. Sharp, lustrous, and translucent calcite rhombs are included with rust-red hematite. Crystals reach 3.7 cm on this piece. The piece is damage-free, impressive for such a large specimen.
12.4 x 7.0 x 3.7 cm. Gem-like, water-clear calcite rhombs with fabulous, striated/stepped-growth faces are aesthetically strewn across the sculptural, cabinet-sized, gossan matrix on this fine specimen from the Tsumeb Mine. The large, perched rhomb is 1.7 cm and many of the rhombs are included with green mottramite, which really adds character. Classic material from this renowned locale. Ex. Rob Smith Collection.
16.0 x 11.5 x 5.8 cm. An impressive, tilted, large cabinet cluster of large, golden-amber calcite scalenohedrons from the famous Joplin Field. The translucent and lustrous crystals have striking, blocky, stepped-growth faces. Interestingly, the two or three large terminations on one end turn into a multitude of doubly terminated crystals on the other end. Nearly pristine, except for trivial edge-wear. Classic, large, old-time material from the George Feist Collection #1660.
12.4 x 7.8 x 5.8 cm. An excellent, classic, old-time, complete-all-around cabinet specimen of sceptered calcite from the Blackstone Mine, Shullsburg, Wisconsin. The off-white scalenohedron is abundantly overgrown with lustrous 1 mm - 1.2 cm rhombohedral calcites in parallel stair-stepped growth. The scalenohedron is capped by a transparent and lustrous, 4.6 x 4.5 cm, complex rhombohedral calcite crystal, which makes for a spectacular sceptered calcite specimen with a striking phantom. Very nearly pristine. Very fine material from the Gene Meieran Collection.
4.7 x 4.5 x 4.3 cm. This intense green emerald is 2.3 cm long, 1.5 cm wide, and glows with color. Not only is it on matrix, or calcite matrix, but it is on crystallized calcite matrix. The calcite crystal atop is about 1 inch across. It makes a great contrast in color and crystal form to the emerald. The emerald is typical in overall hexagonal habit, but atypical in that the surface is minutely detailed, as if somebody took a scribe tool and inlaid a complex cityscape on its surface. The result of this complexity on the apparently smooth outer faces is that the emerald is much more sparkly than you would expect, with all those microfacets reflecting light.
6.4 x 4.1 x 3.4 cm. An excellent cluster of blocky Hydroxyapophyllite on a matrix of gemmy fluorescent Calcite crystals. The Hydroxyapophyllites have superb luster (striated, no less), are partially gemmy, and an attractive light peach color. Note this is not the more common Fluor-variety of apophyllite. This is much rarer, and these crystals are among the worlds finest of this species. The largest crystal is a very significant 3.1 cm long and has superb lustre and translucency. A choice example of a rare species. Ex. Charlie Key.
Gorgeous translucent green octahedrons on an earlier generation of purple/gray fluorite. This is one of the relatively few that are decorated with beautiful dove-gray nailhead calcites. Crystals measure to 4.5 cm on edge. 13.5 x 11.0 x 8.4 cm
Nice Sicilian sulfurs (the world standard) are just getting harder and harder to get. This one has the BRIGHTEST colored TEXTBOOK crystals on an unusually pretty matrix of spiky crystalline calcite. The crystals measure to 1.6 cm tip-to-tip. The beautiful old European specimen came out of the Robert Ray collection. 8.5 x 5.6 x 3.7 cm
deaccessed from the Milton Lavers Collection, this is a rare well-formed, gemmy calcite crystal for Broken Hill. Note the sharp twinning plane in the middle! There are some contacts on the sides, but by and large this is complete and showy, and again quite good for the locality! Better in person... 6 x 4 x 3 cm
